1. Diallel analysis of popcorn populations for yield, popping expansion and resistance to fall armyworm
ABSTRACT The objective of this study was to estimate the varietal and heterotic effects related to grain yield, popping expansion and resistance of popcorn against fall armyworm. Twelve open-pollinated varieties were intercrossed in a complete diallel mating scheme. The 66 experimental hybrids, together with their parents and controls Zapalote Chico, BRS 103

2. GENETIC GAINS IN THE POPCORN POPULATION UENF-14: DEVELOPING THE NINTH GENERATION OF INTRAPOPULATION RECURRENT SELECTION
RESUMO A ocorrência da correlação negativa entre produtividade de grãos (PG) e capacidade de expansão (CE) no milho-pipoca contribui para dificultar o processo seletivo. No intento de contornar esse inconveniente, foi proposto, o caráter de importância, volume por pipoca expandida por hectare (VP). O objetivo deste estudo foi desenvolver o nono ciclo

3. Genetic variability in popcorn synthetic population
ABSTRACT. The Brazilian popcorn has low genetic variability and the successful development of advanced lines, new popcorn cultivars with high grain yield (GY) and expansion volume (PE) is dependent on parental selection and precise determination of heterotic groups. The aim of this study was to evaluate genetic variability and identify heterotic groups in sy

4. The combining ability of popcorn S7 lines for Puccinia polysora resistance purposes
ABSTRACT The present study resulted from the lack of information on the genotypic expression ruling the resistance to rust and on the main traits of economic importance to the herein addressed crop. The combining ability of 16 popcorn lines and hybrids was assessed in partial diallel cross in two representative locations in Rio de Janeiro State, Brazil, wher

5. Inheritance of resistance to Fusarium ear rot in popcorn
Abstract To date, no studies on the inheritance of Fusarium spp. ear rot resistance in popcorn are available. The purpose of this paper was to investigate the additive-dominance model to estimate the genetic components of variance, heritability and the inheritance pattern in a diallel for popcorn, by Hayman’s approach. The experiment was carried out in two

6. Recurrent selection of popcorn composites UEM-CO1 AND UEM-CO2 based on selection indices
ABSTRACT Selection indices were applied to data sets of 169 half-sib families of the popcorn composites UEM-Co1 and UEM-Co2 in four cycles of recurrent selection. From 2005 to 2008, the experiments were arranged in a 13 by 13 lattice square design, with two replications per cycle and composite. Genetic gains for popping expansion (PE) and grain yield (GY) we

7. Analise dialética e heterose de populações de milho-pipoca.
A diallel set of crosses among nine popcorn (Zea mays) cultivars, UNB-2, RS-20, UEM-J1, UEM-M2, CMS 42, CMS 43, Vicosa, Beija-flor and advanced generation of hybrid three-way Zelia, and their hybrid combinations was carried out to obtain heritability and heterosis estimates. The cultivars and F1s were evaluated in two crop years (1998/99 and 1999/2000) with

8. Estimativas de parametros geneticos nas populacoes CMS-42 e CMS-43 de mlho pipoca.
Com os objetivos de elevar a frequencia de alelos favoraveis e estimar os parametros geneticos e fenotipos de algumas caracteristicas agronomicas, as populacoes de milho pipoca CMS-42 e CMS-43 form submetidas ao 2. ciclo de selecao entre e dentro de progenies de meios irmaos. Avaliaram-se 196 progenies de cada populacao, em latice simples 14 x 14, tendo como

9. Relative efficiencies of methods of selection of inbred progenies of popcorn / Eficiência relativa de métodos de seleção de progênies endogâmicas de milho-pipoca
Aiming at to evaluate the relative efficiency of different methods of selection of lines, for production of popcorn hybrid with high productivity and quality, it was aimed at: i) to compare and to evaluate the relative efficiency of the mass selection, selection among and within and combined selection of family following by selection within; ii) to evaluate

10. Eficiencia do processo de secagem do amendoim (Arachis hypogaea L) e milho-pipoca(Zea mays L.)
The artificial drying process is fundamental for agriculture modernization, and is a precondition to store products for long periods of time. Grain drying is an energy intensive and expensive operation. The performance of grain dryers has been measured generally in terms of drying capacity only. In a few cases the energy efficiency are indicated. In the dryi
